types of erasers may be convenientl% cleaned and shaped to render themmore e cient in use. 7

With these and other objects in view, the invention consists in thenovel construction, form and arrangement of the several parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawing, in which:

Figure 1 represents a front elevation of the attachment, a

Fig. Q'represents an end elevation thereof,

Fig. 3 represents a transverse sectional view on the line 33- of Fig. 1,and

Fig. 4 represents a fragmentary perspective view of the shaping elementdetached.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates a substantially semicircular eraser holder constructed ofspring sheet metal and having inwardly directed spring retaining fingers7 struck out from the side walls 6 thereof or secured thereto. Theholder 5 is of adequate size to receive approved types of circularerasers and the spring fingers 7 engage and retain the eraser inposition therein and prevent it from slipping out when the typewriter towhich the device is attached is tilted.

The holder 5 is attached to the typewriter by an attachingclip 8, whichis formed of spring metal and is adapted to embrace any desired part ofthe typewriter to which it is desired to secure the attachment. The freeends of the typewriter engaging members of the clip are clamped inposition by a wing nut 9. I r

A transversely curved strip 10 constituting a support for the erasercleaning and shaping element 11 is provided with laterally projectingears 12, which are suitably fastened to one side wall 6 of the holder.The supporting strip 10 is substantially U- shaped in cross section, asshown in Fig. 3, and the opposed longitudinal edges thereof ,of theelement 11, whereas by movin are provided with inwardly directed flanges13, whichoverlie the edges of the cleaning and shaping element 11 andassist in retaining' the latter in position.

The cleaning and shaping element 11 is preferably constructed of a pieceof curved sheet metal having a roughened inner surface to render itabrasive so as to effectively clean and shape the edge of an eraserinserted therein. A spring clip 14.- is attached to one end of thecleaning and shaping element 11 and embraces'the adjacent end of thesupporting strip 10 to detachably secure the element 11 in positiontherein.

For convenience a pencil supporting clip 15 is attached to the side wallof the eraser holder 5 under the supporting strip 10.

When not in use, the eraser, illustrated in dotted lines in Fig. 1, isinserted in the holder 5 where it is retained against accidental removalby the spring fingers 7. When it is desired to clean the edge of theeraser or reshape it, said edge is inserted in the curved cleaning andshaping element 11 and is moved back and forth across the abradingsurface of the element. Owing to the peculiar formation of the shapingelement 11 the edge of the eraser may be worn down by moving it acrossthe lower portion the side surfaces of the eraser across the si es ofthe element 11 a relatively sharp edge may be produced upon the eraser.

What I claim is:

An eraser cleaner comprising a substan tially U-shaped holder element,inturned flanges at the upper edges of the arms of said holder element,a substantially transversely U-shaped cleaner and shaper element adaptedto be fitted in said holder element and having the upper edges of itsarms positioned beneath the flanges so that the inner RAYMOND H.RAWLEIGH.
